The Kelema Veil and the Nexuses

Leviathalas has a nexus honoring each of Nylea's seasons and the accompanying Karametran planting rituals. There are no temples to other gods in Leviathalas, but offerings to any god may be placed at these holy sites. Under each nexus is a starfield—a vision of Nyx.
As conduits to the various gods, the nexuses are a source of enchantment magic in this region. This phenomenon is called the Kelema Veil. In Leviathalas, oracles can decipher the Kelema Veil. It has been described as a misty starfield that flows across the land. Inside the starfield are images that resemble constellations. These tell stories of the gods and can be used to predict the future.
